GANG-PLOW.

Specification of Letters Patent.

Patented June 6 1916.

Application filed November 3, 1915. Serial No. 59,445.

To all whom it may concern Be it known that I, WILLIAM I. KnMsoN, acitizen of the United States, residing at Niles, in the county ofOttawa, State of Kansas, have invented certain new and usefulImprovements in Gang-Flows; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to gang plows.

' The object of the invention is to provide a gang plow embodying animproved construction for effecting the adjustment of the plow elementsto regulate the depth of the furrow and the angle or pitch at which theplow point enters the ground, the invention being particularly animprovement over the structure disclosed in United States Patent No.1,152,369, granted to myself and Jesse A. Neely, August 31, 1915.

It is also the object of my invention to provide an improved structurewhich will prevent the weight of the tractor being carried on the plowswhen the tractor is passing over uneven ground.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claims.

In describing theinvention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure l is aside elevation of a motor plow embodying the invention, the propellingmechanism for the plowbeing omitted for the sake of clearness; Fig. 2, aplan view of what is shown in Fig. 1; Fig. 3, a section on the line 3-3of Fig. 2; Fig. 4, a section on the line 4-4 of Fig. 2; Fig. 5, asection on the line 5-5 of Fig. 2, and Fig. 6, a section on. the line6-6 of Fig. 2.

Referring to the drawings A indicates the wheel frame of the tractorwhich includes side members 10 and 11, a front member 12, a rear member13, cross members 14 and 15 and a longitudinal member 16 connecting saidcross members. Depending from the side members 10 and 11 are brackets 17in which are rotatably mounted the ends of a bail 18. Pivotally mountedor connected to the bail 18 are the forward-ends of plow beams '19 and20 and said beams'are connected to each other by a bar 21. These beamscarry at their rear ends respectively the usual plows Pivotally mountedon the longitudinal member 16 is an angle lever 23 which carries aspring pawl 24 which cooperates with a segment 25 mounted on the member16. One end of the angle lever 23 is connected to thebail- 18 by meansof a link 25. By operating the lever 23 ,it will be obvious that theforward ends of the plow beams can be raised and lowered for the purposeof regulating the depth of the cut. Mounted on the beams 19 and 20adjacent their rear ends are brackets 26 in which is rotatably mounted abail.27. One end of this bail 27 is slidably engaged in a sleeve 28pivotally mounted on a bracket 29 depending from the side member 11. Theother end of the bail 27 is slidably engaged in a sleeve 30 which ispivotally connected to one end of a link 31. The other end of this linkis in turn pivotally connected to one end of an angle lever 32 whichlatter is pivoted on the side member 10. This lever 32 also carries aspring pawl 33 which cooperates with a toothed segment 34 mounted on themember 10 for the purpose of securing the lever in a desired adjustment.

By operating the lever 32 the structure just described will serve tobring the plows to a level when the tractor wheelie in the furrow and atthe same time secure the plows against sidewise movement. Rotatablymounted in bearings 35 on the rear member 13 is a shaft 36 the ends ofwhich are provided respectively with crank arms 37 and 38. Pivotallyconnected to the free end of the crank arm 37 is a sleeve 39 in which isslidable a rod 40 having one end pivotally connected to a bracket 41secured to the beam 19. The sleeve 39 is held against disengagement fromthe rod 40 by a cotter pin 42. Encircling the rod 40 is a spring 43 oneend of which bears against the sleeve 39 while the other end bearsagainst the bracket 41. Pivotally mounted on the free end of the arm 38is a sleeve 44 in which is slidably mounted a rod 45 provided at one endwith a head 46 to prevent disengagement of the sleeve from the rod. Theother end of this rod 45 is pivotally connected to a lever 47 mountedupon the side member 11 and carrying a spring pawl 48 which cooperateswith a segment 49 for the purpose of. holdingthe lever in a desiredadjustment; The rod45 is provided with a suitable stop 50 and a spring51 encircles said rod and has one end bearing agalnst the stop 50 andits other end against the sleeve 44:; Byproviding the springs 43'" and51 the plows are yieldingly: held-against upward movement at their rearends, said springs ofcourse exerting; a; predetermined downwardpressurefon the'plows.v By this construction ltg will be obvious that :7should. the. tractor; vary inposlt on uplor down-caswould occur intravelover liuievenground the strain willb'e exerted on thespringsand' relievethe plows of the weight of; the:
